Objective : The purpose of study was to verify the clinical effect of a Korean Computer-based cognitive rehabilitation program(called CoTras) for recovering the visual perception function and ADL in stroke. Methods : A CBCRT was applied to 14 Stoke patients who rehabilitation professional medical treatment hospital. All participant were evaluated with four standardized assessment tolls(Motor-Free Visual Perception Test; MVPT, Korean version of Mini-Mental State Examination; MMSE-K, Assesment of Motor and Process Skills: AMPS) before and after the planned computer based cognitive rehabilitation sessions. Results : A significant effect was confirmed (p<.05) from the CBCRT which visual perception function. By each entry comparative result, visual memory, figure ground, visual close, spatial relation, visual discrimination, were the order of treatment. Neither was found any significant effect in improving process skills from AMPS. Conclusion : These results indicate that CoTras have effects on improving visual perception and ADL performance in stroke patients. Will be able to present with the fundamental data CoTras will be able to contribute to increase visual perception function & ADL performance to the stroke patient who has visual perception dysfunction.
